Materials science knowledge base
A working reference for people who specify materials: the periodic table, an engineering materials library with real property ranges, the classes of matter and the crystallography underneath them. No account, no paywall.
Periodic table
Colour-coded by series. Every cell opens a full element page.
SortableElement property table
Mass, density, melting point, electronegativity — all 118, side by side.
37 materialsMaterials library
Steels to semiconductors across 9 categories, with property ranges and processing.
5 classesMaterial classes
How bonding decides behaviour — and what each class costs you.
7 systemsCrystallography
7 systems, 14 Bravais lattices, drawn.
Live dataStructure search
Query the Materials Project, OQMD and OMDB over OPTIMADE.
Browse by element series
Every element in the table belongs to one of these series, and behaves like it.
Browse by material class
Bonding first, properties second — the fastest way to narrow a search.
Metals & Alloys
Metallic bonding — delocalized electron gas; crystalline (mostly FCC, BCC, HCP).
Ceramics & Glasses
Ionic/covalent bonding; crystalline (oxides, carbides, nitrides) or amorphous (glasses).
Polymers & Elastomers
Covalent chains with secondary (van der Waals/H-bond) interactions; amorphous or semi-crystalline.
Composites
Two or more constituents (matrix + reinforcement) combined at macro/micro scale.
Semiconductors & Functional Materials
Covalent (Si, GaAs) or ionic-covalent; band gap defines electronic behavior.

Reference data is the floor, not the ceiling
The knowledge base tells you what a material is. The AI modules tell you which one fits your constraints, how to join it, and what will go wrong.
